Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.

Yet they are limited in terms of negative electrode discharge performance and require high stack pressure during operation. To circumvent these issues, we propose the use of lithium-rich magnesium alloys as suitable negative electrodes in combination with Li6PS5Cl solid-state electrolyte.
Lithium-magnesium binary alloys have been considered one of the most promising alloy negative electrode candidates 14 due to their high energy density, wide solid solubility in the lithium-rich phase and similarity in processing to lithium metal. Conflicting literature reports on diffusivity 20 have contributed to this interest.
These can lead to cells with gravimetric and volumetric energies upwards of 400 Wh ⋅ kg −1 and 1000 Wh ⋅ L −1, which are thermally stable and amenable to fast charging 2. Unfortunately, pure lithium metal negative electrodes struggle to meet the performance requirements of SSBs for EVs. This is due to lithium’s material properties.
The cathode material for the lithium-ion battery is synthesized by baking after mixing the lithium salt with the raw hydroxide. In this case, it also is important to maintain the particle shapes of raw materials by controlling the heating condition.
